摘要

摘要：马毛虫，如变异副原体，表现出打结行为，可能具有调节水分、促进配偶和避免捕食者等多种功能。先前的研究发现，结只由雄性组成，这表明这种行为可能是由聚集性信息素介导的。我们进行了一项定量的实地研究，以确定2018年9月在一条已知有大量成虫的小溪中单独出现的成虫P.varius的相对数量和大小。我们收集了96只马毛虫；均为雄性，与植被有关。我们发现，单独出现的成年雄性变种P.varius明显多于结状，并且它们的长度或干重没有显著差异。实验室中的行为分析可以帮助确定毛虫聚集信息素的可能存在和功能。

Observations on the Occurrence of Knotting Behavior in the Horsehair Worm, Paragordius varius

abstract: Horsehair worms, such as Paragordius varius, exhibit knotting behavior that may serve various functions such as water regulation, mate facilitation, and predator avoidance. Previous studies have found knots consisting only of males, suggesting that this behavior may be mediated by an aggregation pheromone. We conducted a quantitative field study to determine the relative number and size of adult P. varius that occur singly and in knots in a creek known to have a large number of adults in September of 2018. We collected 96 horsehair worms; all were male and associated with vegetation. We found significantly more adult male P. varius occurring singly than in knots and found no significant difference in their length or dry weight. Behavioral assays in the lab can help determine the possible presence and function of hairworm aggregation pheromone.

期刊介绍： Comparative Parasitology (continuing the Journal of the Helminthological Society of Washington in its 67th volume) focuses on parasitological research of a comparative nature, emphasizing taxonomy, systematics, ecology, biogeography, evolution, faunal survey, and biological inventory within a morphological and/or molecular context. The scope of Comparative Parasitology extends to all parasitic faunas, including helminths, protistans and arthropods.
